Definitions

  • a number of smoking articles in which tobacco is heated rather than combusted have been proposed in the art.
  • An aim of such ‘heated’ smoking articles is to reduce known harmful smoke constituents of the type produced by the combustion and pyrolytic degradation of tobacco in conventional cigarettes.
  • an aerosol is generated by the transfer of heat from a combustible heat source to a physically separate aerosol-forming substrate located downstream of the combustible heat source.
  • volatile compounds are released from the aerosol-forming substrate by heat transfer from the combustible heat source and entrained in air drawn through the smoking article. As the released compounds cool, they condense to form an aerosol that is inhaled by the user.
  • WO-A2-2009/022232 discloses a smoking article comprising a combustible heat source, an aerosol-forming substrate downstream of the combustible heat source, and a heat-conducting element around and in direct contact with a rear portion of the combustible heat source and an adjacent front portion of the aerosol-forming substrate.
  • the heat-conducting element and the aerosol-forming substrate are circumscribed by an outer wrapper of paper.
  • the temperature attained in the aerosol-forming substrate has a significant impact on the ability to generate a sensorially acceptable aerosol. It is typically desirable to maintain the temperature of the aerosol-forming substrate within a certain range in order to optimise the aerosol delivery to a user.
  • smoking articles comprising a combustible heat source and an aerosol-forming substrate located downstream of the combustible heat source
  • movement of the combustible heat source relative to the aerosol-forming substrate during use of the smoking article may cause the temperature of the aerosol-forming substrate to drop outside of a desired range, thereby impacting the performance of the smoking article. If the temperature of the aerosol-forming substrate drops too low, for instance, it may adversely impact the consistency and the amount of aerosol delivered to a user.
  • a number of ways of retaining combustible heat sources in position within heated smoking articles have been proposed. For example, it is known to apply a layer of glue around the combustible heat source, between the combustible heat source and the wrapper. However, if the glue is combusted during use, the combustible heat source may be held in place only by the wrapper. This may lead to movement of the combustible heat source relative to the aerosol forming substrate if the holding force applied by the wrapper is insufficient.
  • wrap the wrapper has also been proposed to wrap the wrapper tightly around the combustible heat source, or to extend the wrapper such that it circumscribes the entire length of the combustible heat source.
  • the wrapper may adversely affect combustion of the heat source by restricting the air supply, which may lead to a drop in the temperature of the aerosol-forming substrate and an adverse impact on the consistency and the amount of aerosol delivered to a user.
  • the pressure generated by combustion gases produced by the combustible heat source may build up behind a tightly wrapped wrapper.
  • the wrapper can be applied tightly around the combustible heat source to hold it in the correct position while still allowing a sufficient supply of air to the combustible heat source and allowing combustion gases generated by the heat source to escape through the plurality of apertures during use.
  • This ensures that the conductive heat transfer from the heat source to the aerosol forming substrate, and consequently the performance of the aerosol generating article, is maintained. It may also remove the need for glue to be applied around the combustible heat source, simplifying manufacture.
  • the weakness formations are arranged such that the wrapper ruptures at the weakness formations for example under the pressure generated by combustion gases.
  • the wrapper forms a barrier prior to rupture, for example to restrict the amount of moisture absorbed from the atmosphere by the heat source during transportation and storage. As moisture may hinder the heating performance of the heat source, restricting the amount of moisture absorbed by the heat source may have a positive impact on the performance of the aerosol generating article.
  • weakness formations refers to structural weaknesses in the wrapper arranged to facilitate tearing or breakage of the wrapper at predefined positions to form apertures with predefined shapes and dimensions.
  • the structural weaknesses may be formed for example through removal or destruction of some of the material in that portion for example laser ablation or other method, or through mechanical pressing or rolling without removing material.
  • the term “weakness formations” includes lines of weakness, along which the wrapper material has been weakened, and areas of weakness across which the wrapper material has been removed.
  • Aerosol generating articles comprise a proximal end through which, in use, an aerosol exits the article for delivery to a user.
  • the proximal end of the aerosol generating article may also be referred to as the mouth end or the downstream end.
  • a user draws on the mouth end of the aerosol generating article.
  • the mouth end is downstream of the distal end.
  • the combustible heat source is located at or proximate to the distal end.
  • the distal end of the aerosol generating article may also be referred to as the upstream end.
  • Components, or portions of components, of the smoking article may be described as being upstream or downstream of one another based on their relative positions between the proximal end of the smoking article and the distal end of the smoking article.
  • the front of a component, or portion of a component, of the aerosol generating article is the portion at the end closest to the upstream end of the aerosol generating article.
  • the rear of a component, or portion of a component, of the aerosol generating article is the portion at the end closest to the downstream end of the aerosol generating article.
  • the rear portion of the combustible heat source is the portion of the combustible heat source at the downstream end of the combustible heat source.
  • the front portion of the aerosol forming substrate is the portion of the aerosol forming substrate at the upstream end of the aerosol forming substrate.
  • the one or more lines of weakness preferably do not extend through the thickness of the wrapper. With such an arrangement, the wrapper may form a barrier prior to rupture, even in the regions defined by the weakness formation.
  • one or more of the weakness formations may have a circumferential dimension of at least about 0.5 mm, preferably from about 0.5 mm to about 2.6 mm, more preferably from about 0.8 mm to about 1.8 mm.
  • each of the weakness formations has a circumferential dimension of at least about 0.5 mm, preferably from about 0.5 mm to about 2.6 mm, more preferably from about 0.8 mm to about 1.8 mm.
  • the wrapper is substantially impermeable to air. That is, the wrapper is formed from one or more materials that are substantially impermeable to air. With such an arrangement, the wrapper forms a substantially airtight barrier around the combustible heat source. This may substantially prevent absorption of moisture from the atmosphere by the combustible heat source through the wrapper.
  • the weakness formations may be provided on the wrapper such that the ventilation zone extends along substantially the entire length of the region of the wrapper overlying the combustible heat source.
  • the wrapper may be in indirect contact with an outer surface of the combustible heat source via one or more intermediate components.
  • the wrapper may be in direct contact with an outer surface of the combustible heat source.
  • the wrapper may be in direct contact with the outer surface of the combustible heat source along substantially the entire length of the region of the wrapper overlying the combustible heat source.
  • Aerosol generating articles according to the present invention comprise a combustible heat source for heating the aerosol forming substrate.
  • the combustible heat source is preferably a solid heat source, and may comprise any suitable combustible fuel including, but not limited to, carbon and carbon-based materials containing aluminium, magnesium, one or more carbides, one or more nitrides and combinations thereof.
  • Solid combustible heat sources for heated smoking articles and methods for producing such heat sources are known in the art and described in, for example, U.S. Pat. No. 5,040,552 and U.S. Pat. No. 5,595,577.
  • known solid combustible heat sources for heated smoking articles are carbon-based, that is they comprise carbon as a primary combustible material.
  • Aerosol generating articles according to the invention comprising blind combustible heat sources comprise one or more air inlets downstream of the rear end face of the combustible heat source for drawing air into one or more airflow pathways through the aerosol generating article.
  • Aerosol generating articles according to the invention comprising non-blind combustible heat sources may also comprise one or more air inlets downstream of the rear end face of the combustible heat source for drawing air into one or more airflow pathways through the aerosol generating article.
  • aerosol-forming substrate is used to describe a substrate capable of releasing upon heating volatile compounds, which can form an aerosol.
  • the aerosols generated from aerosol-forming substrates of aerosol generating articles according to the invention may be visible or invisible and may include vapours (for example, fine particles of substances, which are in a gaseous state, that are ordinarily liquid or solid at room temperature) as well as gases and liquid droplets of condensed vapours.
  • the aerosol-forming substrate may be a rod comprising a tobacco-containing material.
  • the transfer element may abut one or both of the aerosol-forming substrate and a mouthpiece. Alternatively, the transfer element may be spaced apart from one or both of the aerosol-forming substrate and the mouthpiece.
  • a transfer element advantageously allows cooling of the aerosol generated by heat transfer from the combustible heat source to the aerosol forming substrate.
  • the inclusion of a transfer element also advantageously allows the overall length of the aerosol generating article to be adjusted to a desired value, for example to a length similar to that of a conventional cigarette, through an appropriate choice of the length of the transfer element.
  • an aerosol-generating article is used to denote an article comprising an aerosol-forming substrate that is capable of releasing volatile compounds that can form an aerosol.
  • An aerosol-generating article may be a non-combustible aerosol-generating article, which is an article that releases volatile compounds without the combustion of the aerosol-forming substrate.
  • An aerosol-generating article may be a heated aerosol-generating article, which is an aerosol-generating article comprising an aerosol-forming substrate that is intended to be heated rather than combusted in order to release volatile compounds that can form an aerosol.
  • a heated aerosol-generating article may comprise an onboard heating means forming part of the aerosol-generating article, or may be configured to interact with an external heater forming part of a separate aerosol-generating device.
  • Adjacent weakness formations 450 in longitudinally aligned alternate rows are separated in the circumferential direction by a circumferential separation 456 .
  • Adjacent weakness formations 450 in each row are separated in the longitudinal direction by a longitudinal separation 457 .
  • the circumferential separation 456 is at least about 0.5 mm, preferably from about 0.5 mm to about 2.5 mm, more preferably from about 0.7 mm to about 1.5 mm.
  • the longitudinal separation 457 is at least about 0.4 mm, preferably from about 0.4 mm to about 1.8 mm, more preferably from about 0.5 mm to about 1.3 mm
